TNG: "Time Squared" and "The Hunted" both stated that shuttlebays two and three were on Deck 11. However, the shuttlebays actually spanned Decks 12 and 13 on the Enterprise miniature. The error was corrected in subsequent episodes. Cargo bay four also moved betwen the fifth and sixth seasons; in TNG: "Power Play," it was on Deck 18, while in TNG: "Schisms" it was now on Deck 4.

The Enterprise-D carried twelve phaser arrays, three torpedo launchers, a complement of 250 photon torpedoes, and a high capacity shield grid (TNG: "Conundrum"); there are some 4000 power systems in all onboard the ship. The ship also had twenty transporter pads. (TNG: "11001001")

The crew

In 2367, an average day aboard ship recorded by Lieutenant CommanderData, included four birthdays, two personnel transfers, two chess tournaments, a secondary school play, four promotions, and at least one birth. (TNG: "Data's Day") The Enterprise normally ran on four duty shifts. (TNG: "Lower Decks") Reducing to three duty shifts would cause many personnel scheduling problems, as when Captain Jellico ordered a change during his tenure as captain in 2369. (TNG: "Chain of Command, Part I") Crew evaluations were conducted every three months, and were usually supervised by Will Riker and Deanna Troi. (TNG: "Lower Decks")

Although Starfleet crewmembers staffed the vital positions onboard the Enterprise, civilian crewmembers were allowed to hold important jobs in the ship's science and medical departments, as well as support areas like Ten Forward and the ship's school. (TNG: "Night Terrors," "Hero Worship," "Ethics")

In service

The Enterprise-D made first official contact with a number of species. (See below.)

Later in 2364, the Enterprise was hijacked from Starbase 74 by the Bynars. They intended to use the ship to repair the damaged computer on their homeworld. The Enterprise was returned to Captain Picard's custody following the incident, and the Bynars freely accepted the consequences of their actions. (TNG: "11001001")

During its first encounter with the Borg, sections 27, 28, and 29 on decks 4, 5 and 6 were removed for analysis by the Borg, killing eighteen people. (TNG: "Q Who?") During the Borg incursion of 2366 and 2367, the Enterprise suffered heavy damage. Deck 36, including Main Engineering, was decompressed after a cutting beam damaged the engineering hull, killing eleven and possibly eight more. (TNG: "The Best of Both Worlds, Part I") The main deflector dish was transformed into a last-ditch energy weapon, which failed due to the assimilated knowledge of Captain Picard. In the attempt, the deflector and warp core were overloaded, while several decks were flooded with radation. Later, the saucer module sustained damage to its impulse drive and decks 23 through 25 were sliced open by the enemy during the final battle over Earth. (TNG: "The Best of Both Worlds, Part II) The extent of the damage required a full refit at Earth Station McKinley which lasted 5 to 6 weeks. (TNG: "Family")

During that refit, the starship received a phaser upgrade as well as full damage repair and a new dilithium chamber articulation frame. The frame malfunctioned later that year, causing extensive damage to the warp core. Although Romulan sabotage was initially suspected, it was later learned that undetectable flaws in the hatch were responsible. (TNG: "The Drumhead")

The Enterprise was repeatedly destroyed in 2368, when the ship was trapped in a temporal causality loop near the Typhon Expanse. Each cycle ended in a catastrophic collision with the USS Bozeman. Feelings of deja vu allowed the Enterprise crew to gather clues which allowed them to send a message into the next loop and avoid the collision. The ship spent a total of seventeen days repeating the same interval of time. (TNG: "Cause and Effect")

The Enterprise was one of the first Starfleet vessels to dock at the newly commissioned Deep Space 9, where it offloaded most of the station's Starfleet contingent and its first compliment of runabouts. (DS9: "Emissary")

The Enterprise underwent its first baryon sweep at the Remmler Array in 2369. A stronger field was needed due to the Enterprise's heavy use of warp drive. During the sweep, a mercenary group nearly stole dangerous trilithium resin from the warp core, but was thwarted by the Enterprise senior staff. (TNG: "Starship Mine")

Late in 2369, the Enterprise was damaged while rescuing the crew of a Romulan warbird. Its warp core had been colonized by lifeforms which mistook it for a genuine quantum singularity, causing severe disruptions in space-time. The Enterprise was nearly destroyed due to feedback from a power transfer beam, which was killing the lifeforms' young. Fortunately, several Enterprise crewmembers were returning to the ship at the time and were able to rescue the Enterprise and the Romulan crew. (TNG: "Timescape")

The new warp core was gone by the next episode, suggesting the upgrades were not completed due to the problems with the interphasic manufacturing technique. Curiously, the upgraded hatch appeared in one of the universes visited by Worf in "Parallels."

Also during 2370, Commander La Forge engaged in a friendly contest with Donald Kaplan, chief engineer of the USS Intrepid. They competed to have the best power conversion rates in the fleet, with the Enterprise frequently beating out the Intrepid. (TNG: "Force of Nature")

The Enterprise became one of the few Federation ships to use a cloaking device in 2370, and perhaps the first to successfully use a phasing cloak. It had been retrieved from the wreckage of the USS Pegasus and was installed aboard the Enterprise to allow it to pass through an asteroid after a Romulan vessel sealed the ship inside. (TNG: "The Pegasus")

While investigating a rogue comet in 2370, the Enterprise stumbled upon an archive of the lost D'arsay civilization. The archive trapped the ship and used matter and DNA aboard to create artifacts from the D'arsay culture. The Enterprise was later returned to normal. (TNG: "Masks")

In early 2371, the Enterprise received a number of refits to its internal spaces. Color and lighting schemes were slightly altered, and the bridge inherited a number of new consoles on the port and starboard sides. There were now four science stations, three along the starboard wall and one at the starboard side of the aft stations. Mission Ops was now the second station, followed by Environment. Two engineering stations rounded out the aft area, while three communications stations were now present along the port wall.

The Enterprise was lost in 2371 after an attack by renegade Klingon caused extensive damage, leading to a warp core breach. Although the saucer section was safely separated before the breach, the force of the explosion shoved it into the atmosphere of Veridian III. Fortunately, Commander Deanna Troi was successful in maneuvering the saucer to a safe landing, and losses were minimal. The ship, however, was unsalvageable, and the crew was rescued by the USS Farragut. Commander Riker was upset over the loss of the Enterprise, as he hoped he would one day command the ship. (Star Trek: Generations)

The Enterprise also encountered the Paxans in 2367 during TNG: "Clues," but all recollection of that encounter was erased from memories and ship's logs. Furthermore, the Enterprise may not have been the first Starfleet ship to stumble upon the Paxans.

Alternate Enterprises

"Time Squared"

One alternate version of the Enterprise was observed in 2365. A ship from several hours in the future was destroyed following an encounter with a spatial anomaly, which was later determined to be a sentient presence. There was a single survivor, Captain Picard, who was thrown back in time and picked up by the Enterprise. The other Picard was able to determine that the Enterprise needed to fly through the anomaly rather than attempt to escape it via the entrance, and the timeline was averted. (TNG: "Time Squared")

"Yesterday's Enterprise"

In another alternate timeline, following the disapperance of the USS Enterprise-C, and the destruction of the Klingon outpost at Narendra III, relations between the Federation and the Klingon Empire deteriorated into war.

The Enterprise-D in this alternate timeline was the first of the Galaxy-class warships constructed by the Federation, capable of carrying over 6,000 troops. The vessel was entirely militarized, with no civilian compliment or counselor. The bridge contained multiple redundant consoles, with a single command chair for the captain. Replicators throughout the ship were restricted to minimal power, and all available power was routed to the defensive systems.

In 2366, on combat date 43625.2, the Enterprise-D investigated a radiation anomaly near Starbase 105, where it encountered the Enterprise-C, transported through time by the anomaly, a temporal rift. As the Enterprise-D assisted in repairs, it was made clear that the Enterprise-C had to return through the rift, in order to prevent the chain of events that would lead to war. Enterprise-D crewmember Guinan was aware of the change to the timeline, and convinced Captain Picard to send the Enterprise-C back through the rift.

The Enterprise-D laid down cover fire in order for the Enterprise-C to return through the rift. Heavy casualties were suffered, and the vessel was on the verge of a warp core breach when the timeline was restored. However, the Enterprise-C crew retained memories of their encounter, and one Enterprise-D crewmember, Natasha Yar, went back in time with the Enterprise-C. (TNG: "Yesterday's Enterprise," "Redemption, Part II")

"Remember Me"

In 2367, the thoughts of Dr. Beverly Crusher after she was trapped in a warp bubble created a completely separate universe, in which people and objects began disappearing. At various points, the crew of the Enterprise was reduced to a normal operating contingent of about 300, then 100, then simply 2. All crew eventually disappeared, as the bubble began to collapse and the universe destroyed. This Enterprise was gradually erased from existence as the bubble collapsed. (TNG: "Remember Me")

"Parallels"

Several thousand Enterprises from many different quantum realities spilled into a single universe in early 2370. This was due to Lieutenant Worf's encounter with a quantum fissure, and the attempts to return him to his proper universe. The fissure was eventually sealed and the ships returned to their proper universes, although one Enterprise, from a universe where the Borg had emerged victorious from the Battle of Wolf 359 and subsequent events, was lost as it attempted to prevent its return to its own reality. When Worf returned to his normal universe, time was reversed and these events no longer occurred. (TNG: "Parallels")

"All Good Things..."

Several alternate versions of the Enterprise-D were seen by Captain Picard after encountering the anti-time eruption in the Devron system caused by the Q entity. All were part of separate closed timelines.

In the anti-time past of 2364, the Enterprise was not sent to Farpoint Station, but instead was diverted to investigate the anomaly, which was feared to be a new Romulan presence. In this time period, Picard did not inform his crew of his time shifts, worrying that it may influence the future. He initally ignored Starfleet's orders and proceeded to Farpoint, but then diverted the ship to the Devron system and began scanning the anomaly with an inverse tachyon beam. When it was discovered that the beam actually caused the anomaly and that the ship would need to create a static warp shell to contain the eruption, the crew was hesitant to accept the orders of their commander, who seemed to be making arbitrary decisions. After a quick reassurance from Picard, the crew cooperated and the ship joined the two other Enterprises in order to seal the breach. It was first to be destroyed after the stress from the static warp shell caused a warp core breach.

The second ship existed in 2370. Its history was identical to the real ship up until that point. It was also sent to the Devron system, and began to scan it with the inverse tachyon beam. Picard did tell this crew about his time shifts. This Enterprise joined the two other ships inside the anomaly, but was also destroyed trying to maintain a static warp shell.

In the anti-time future, the Enterprise was not destroyed at Veridian III, but remained in service until at least the early 25th century, where Admiral Riker had saved the vessel from being decommissioned by making it his personal flagship based out of Starbase 247. In this alternate future, the ship had undergone several significant modifications, including the addition of a third nacelle, a cloaking device, and a large phaser weapon mounted underneath the saucer section. It single-handedly destroyed one Klingon battleship and forced another to retreat while rescuing the USS Pasteur crew, following their attempt to find the anomaly. Riker ordered the Enterprise back to Federation space, but Picard later convinced him to return to the Devron system and the ship arrived in time to watch the initial formation of the anomaly. It was the last ship to be destroyed in the attempt to seal the anomaly. (TNG: "All Good Things...")

The exact date of the future events shown in "All Good Things..." is not known. It is possible it took place in 2395, but this is assuming that the Enterprise crew broke up immediately following the end of the series. Picard merely said it had been twenty-five years since the crew had been together on the Enterprise. It is equally likely that the crew was together until 2376, when Deanna Troi died.

Background Information

The three miniatures used to represent the Enterprise-D: from front to back, the two-footer, the four-footer, and the six-footer.

The Enterprise model was designed by Andrew Probert. Two versions were built by Industrial Light and Magic for the first season, a large six-foot model and a smaller two-foot model. Both were capable of saucer separation. For the third season, Greg Jein built a new four-foot miniature. It was not built to separate, but for the first time it accurately depicted the Ten Forward windows. It first appeared in TNG: "The Defector" and completely replaced the previous two models, although stock footage of the original models was still used. The six-foot model was briefly reused for the saucer separation in TNG: "The Best of Both Worlds, Part II." It was completely refurbished and overhauled for Star Trek: Generations, where it represented the Enterprise alongside a computer generated version and a special twelve-foot wide saucer, created for the crash sequence. ILM crewmember Bill George relabeled the registry on the saucer to "NCC-1701-E" before the model was returned to the Paramount archives. The four-foot model was modified into the three-nacelled Enterprise from TNG: "All Good Things..." and later restored to become the USS Odyssey in DS9: "The Jem'Hadar" and the USS Venture in DS9: "The Way of the Warrior." It may have also been labeled as the USS Trinculo at some point during DS9's run.

The Enterprise-D also made a brief appearance at the end of the Star Trek: Armada strategy game.
